7014 CDGB/P4A Bearing Product Overview & Core Advantages
The 7014 CDGB/P4A is a precision angular contact ball bearing designed for high-performance applications requiring exceptional rotational accuracy and rigidity. This single bearing features a 15° contact angle and is universally matchable (SU), allowing for precise axial preload adjustment when paired with another identical bearing. Its P4A tolerance class ensures ultra-precision operation, making it ideal for machine tool spindles and other high-speed, high-rigidity systems. The bearing comes pre-lubricated and is capable of handling significant combined loads.

| P4A | High precision tolerance class for superior running accuracy. |
7014 CDGB/P4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with a 15° contact angle enables the bearing to efficiently support combined radial and axial loads. The optimized internal geometry and high-quality chrome steel construction provide exceptional stiffness, minimizing deflection under load.
High-Speed Performance: The lightweight phenolic cage ensures stable operation and reduces centrifugal forces, contributing to a high limiting speed of 22,000 rpm. This makes it an excellent choice for high-speed spindle applications.
Precision & Longevity: Manufactured to P4A tolerance standards, this bearing guarantees minimal runout and vibration. The open seal type allows for efficient re-lubrication in demanding applications, while the standard lubrication and wide temperature range (-30°C to 110°C) ensure reliable performance.
